【考案の詳細な説明】
この考案は車輛（特に大型車輛）の左折時に生ずる前輪
１と後輪１０との回転半径の差に起因する事故を防止す
るためのものである。[Detailed Description of the Invention] This invention is intended to prevent accidents caused by the difference in turning radius between the front wheels 1 and the rear wheels 10 that occur when a vehicle (particularly a large vehicle) turns left.
従来は後輪用フェンダ−の幅を拡げたり又は車輌側面に
防護柵を固定的に取付けたりして、左折時、後輪１０に
人又は物が巻き込まれるのを防止したが、それだけでは
事故の発生を完全に防止することが出来なかった。Conventionally, the width of the rear wheel fender was widened or a protective fence was fixedly attached to the side of the vehicle to prevent people or objects from getting caught in the rear wheel 10 when turning left, but this alone could prevent accidents. It was not possible to completely prevent the occurrence.
本案はその欠点を除（ために考案されｆこもので。This proposal was devised to eliminate that drawback.
之を図面について説明する。This will be explained using the drawings.
かじとりハンドル５の反時計式回転が機械的、電気的又
は油圧その他を用いる方法で、連結棒７を車輛の外部方
向（図面に従えば左方）へ駆動し。Counterclockwise rotation of the steering handle 5 mechanically, electrically, hydraulically or otherwise drives the connecting rod 7 towards the exterior of the vehicle (to the left according to the drawings).
それにより入子型（テレスコ−ビック）外部防護柵１１
と１３が外部にふくれる。Therefore, telescopic external protective fence 11
and 13 swell outside.
図面によるかじとりハンドル５と連結棒７の連結は機械
的なそれを示す一例である。The connection between the steering handle 5 and the connecting rod 7 shown in the drawings is an example of a mechanical connection.
車輌が左折すべくかじとりハンドルが反時計式に回転せ
しめられると、かじとり軸３に取付けられたラチェット
機構内蔵プーリー２が同方向に回転する。When the steering wheel is rotated counterclockwise to turn the vehicle to the left, a pulley 2 with a built-in ratchet mechanism attached to a steering shaft 3 rotates in the same direction.
一端をプーリー２に固定され、他端は駆動力１．８の一
端に固定された一定の長さのロープ４はかじとりハンド
ル５０回転に従い駆動力１．８の一端を引張り、連結棒
７を外部方向へ押しやる。A rope 4 of a certain length, with one end fixed to the pulley 2 and the other end fixed to one end of the driving force 1.8, pulls one end of the driving force 1.8 as the steering wheel rotates 50 times, and connects the connecting rod 7 to the outside. push in a direction.
外部防護柵１１と１３はその前後両端が車輛シャーシに
固定せられ、その枠が入子型となっているので支点１２
に力が加えられると外部へ自由にふくらみ又は元の位置
に自由に戻り得る構造となっている。The front and rear ends of the external protection fences 11 and 13 are fixed to the vehicle chassis, and their frames are telescopic, so the fulcrum 12
It has a structure that allows it to freely bulge outward or return to its original position when force is applied to it.
連結棒γが外部方向に押しやられるとぎ、この動作は支
点１２を通じ外部防護柵１１と１３を外部方向にふくれ
さす。When the connecting rod γ is pushed outward, this movement bulges the external guardrails 11 and 13 outward through the fulcrum 12.
柵では間隙が生ずるので、之に板を取付けるのも一策で
ある。Since gaps are created by fences, it is also a good idea to attach boards to them.
車輛の左折が完了し、かじとりハンドル５が元の位置に
戻されたときはスプリング６の力により連結棒７は元の
位置に戻り、外部防護柵１１と１３もふくらみの位置よ
り元の位置に戻る。When the left turn of the vehicle is completed and the steering handle 5 is returned to its original position, the connecting rod 7 is returned to its original position by the force of the spring 6, and the external protection fences 11 and 13 are also returned to their original positions from their bulged positions. return.
車輛の直進の時は外部防護柵１１と１３はふくらまない
。When the vehicle is traveling straight, the external protective fences 11 and 13 do not inflate.
車輌の右折の時はプーリー２に内蔵されたラチェット機
構によりロープ４は駆動されない。When the vehicle turns right, the rope 4 is not driven by the ratchet mechanism built into the pulley 2.
車輛の左折時、外部防護柵１１と１３に人又は物が接触
するとぎは、その衝撃を成る程度、運転者はかじとりハ
ンドル５に感じ得る。When a person or object comes into contact with the external protective fences 11 and 13 when the vehicle turns left, the driver can feel the impact to a considerable extent on the steering wheel 5.
本案は上記の様な機構であるので車輛（特に大型車輛）
の左折時に於ける後輪巻込み事故を効果的に防止する。This project has the above mechanism, so it is suitable for vehicles (especially large vehicles).
To effectively prevent accidents involving rear wheels when turning left.
